Economic Crime and Corporate Transparency Act 2023  

The Economic Crime and Corporate Transparency Act became law on 26th October 2023. Over the coming years this will have significant effect on the way Companies House operates and will ultimately lead to reforms in the public register. More immediately, there are some imminent changes to certain forms as detailed below. 

  • Change of registered office address (AD01 and LL AD01) will be effective from 4th March 2024. 
  • Confirmation Statement (CS01 and LL CS01) will be effective from 5th March 2024. 


The following changes have been made, to ensure the software is compliant: 

  • A registered email address will be required on the first Confirmation Statement (LL)CS01 submitted after the effective date for existing businesses. This means that the email address provided will be registered with Companies House and used for all future communication from them. The Registered email address can be any email address including the agent’s email address, if that’s relevant and must be one that is regularly checked as Companies House will be using this to send any correspondence. 
  • A lawful purpose declaration is required for submission of the Confirmation Statement for a Limited Company (CS01) and Limited Liability Partnership (LLCS01), and can be selected when you log the event 
  • An appropriate address declaration is required for the submission of the Change of a Company’s Registered office address (AD01) and Change of a Registered office address of a Limited Liability Partnership (LLAD01) and can be selected when you log the event. 
  • The paper version of the Confirmation Statement for both Limited companies and Limited Liability Partnerships will not be available in this release and we will look to include in a future release. 
  • For both incorporated charities and charitable trusts the new CS01 and AD01 in either paper or electronic form will not be supported by this release.  This will be resolved in the next appropriate release. 

Should you have any existing forms that have a date or a made-up date prior to 4th March (or for Confirmation statements 5th March), then where practically possible we recommend you file these so that they will be accepted in their existing form. Beyond that date Companies House will be enforcing new filing schemas and forms, the schemas that predate 4th and 5th March will then be retired by Companies House. The software will adopt all the new electronic schemas from the dates above onwards.

iXBRL Taxonomy update 

From 1st April 2024 Companies House will be implementing some changes which alter the validation where a revised or amended dimension is used in the accounts. As part of this release, we have implemented a change to the way the accounts are tagged to allow electronic filing to continue unhindered.
